High-Power, 3-Micron, Fiber-Based Laser System Navy SBIR FY2013.2 Sol No.: Navy SBIR FY2013.2 Topic No.: N132-106 Topic Title: High-Power, 3-Micron, Fiber-Based Laser System Proposal No.: N132-106-0552 Firm: Q Peak, Inc. 135 South Road Bedford, Massachusetts 01730-2307 Contact: Bhabana Pati Phone: (781) 275-9535 Web Site: www.qpeak.com Abstract: The Navy has identified tactical applications for 3000-nm-wavelength-region lasers, which feature very high efficiency in coupling laser energy to water. This is the result of the most intense infrared absorption band for liquid water, which has a broad peak centered at 2900 nm, with an absorption coefficient of 10000 /cm. Development of lasers in the region has, in the past, been driven primarily by medical applications that rely on the absorption by tissue for the 2800-2900-nm wavelength range, a result of the high water content of most tissues. The Navy requires average powers exceeding 100 W and high beam quality, and this proposal addresses how this may be accomplished. The work we propose centers on the development of fiber lasers, doped with Er ions. Benefits: The 3-micron high-power source is needed by the Navy for tactical applications. Besides Navy requirements there are medical applications in precision surgery and in remote sensing systems that require high powers in the infrared wavelength region. Return
